Hi everyone,<br><div class="gmail_quote"><br>Just a note for anyone analysing g13b data, the dataset where the coherent edge was supposed to be set at 1.5 GeV contains a freak batch of runs where it had obviously been accidentally set at 1.7GeV (see plot attached, shows coh edge for both PARA and PERP summed, in spite of what the title says). There is nothing about that in the log book as far as I could find, and it's labelled as 1.5 in the run data table and on the wiki.<br>
<br>These are in the Ee = 4065MeV batch, run numbers 55048 - 55082 inclusive. <br><br>I would treat that data with caution, in terms of applying polarisation values to it, as I saw some significant systematics between asymmetries calculated from it and the rest of the data at the same energies. Anywhere up to 40% or so.<br>
